Building a Cash Register Project with Python

I am working on a project in Python about the development of a cash register system and would like to ask for some guidance or suggestions on how to approach this task. The object of the project is to provide a simple cash register that can handle different transactions, show totals, apply discounts, and give out receipts. I would like this project to be as efficient and user-friendly as possible.

Well, here are a few concrete areas where I might want some advice from the community:

Designing the interface: Should I focus on the command-line interface or integrate a GUI? What kind of libraries would be ideal in either case?

Transaction Handling: How best to code the handling of multiple transactions happening all at once? Are there any libraries in Python that could enhance transaction management or keep a record of sales?

I also wanted to say that, regarding Python, I’ve been playing around on this Python Online Compiler site. That’s a pretty cool tool to do quick tests and runs of Python code, in fact. That’s been very useful so far in prototyping different components of the cash register system.

Calculations of Totals and Discounts: How would be the best practice with regard to the implementation of functions designed to calculate totals and discounts? Should these be modularized into different functions or classes?

Generating Receipts: I want to make sure the receipts are well formatted and contain all information on an average receipt, such as itemized lists, totals, and any discounts if applicable. What libraries and tools can I use to effectively format and print these receipts?

Testing and debugging: do you believe that there are certain techniques or Python-specific tools in which you should employ to test and debug this project? In what ways can I assure this is going to be a reliable cash register system?

Insights, suggestions, or examples from others who may have completed similar projects would be very much welcome. Thanks!
